Yes, it is very likely that Youri Tielemans will fall into the hands of Arsenal or Barcelona, but on the other hand, it is reported that Leicester coach Brandan Rodgers will retain Tielemans with a salary increase offer.
Yes, maybe you are right Tielemans is one of the midfielders who wants to come to Arsenal, but Tielemans is still under contract with Leicester for another 11 months, at least Arsenal can be patient to bring Tielemans to the Arsenal club, than Arsenal have to buy Tielemans in the current contract period with Leicester, at a price of 32 million Pounds Sterling, that may be quite a price in the contract period of 11 months, after that Arsenal have to make a new contract with Tielemans.
Apart from the Barcelona club who want to bring in Tielemans, Man United also wants Tielemans to join their club, it seems that Tielemans is a bone of contention and the target of big clubs, it seems that Tielemans prefers Arsenal over other clubs, hopefully Tielemans will consider the decision wisely and maturely in the future.
